Intentionally risky patterns in one sandbox

Most of the “issues” are classic footguns — mutable defaults, bad open usage, weird conditionals, shadowing builtins, pdb, insecure temp files, shell=True, etc. — all concentrated in a single, isolated file.
That lines up with the “programming patterns” note: this reads like a grab‑bag of what-not-to-do, kept modular so nothing leaks out.

Import alias same as package name is unnecessary

The import statement uses import sys as sys, which creates a redundant alias identical to the original package name. This does not simplify or change usage and may confuse readers or maintainers. Remove the unnecessary alias to clean up the import and improve clarity.

Remove the as sys alias and use a simple import sys statement instead to eliminate redundancy and improve code readability.

`pdb` import risks accidental debug code in production

Importing the pdb module allows insertion of breakpoints that pause program execution for debugging. If left in production code, it may halt the application unexpectedly or expose sensitive runtime information.

Remove the import pdb line and any associated debugging calls before committing code to production to avoid interruptions or accidental exposure.

Unused `sys` import increases code clutter

The sys module is imported as sys but never used in the module, which adds unnecessary code clutter and can mislead maintainers or static analysis tools. It also increases the cognitive load when reading the code.

+    f = open("/tmp/.deepsource.toml", "r")
+    f.write("config file.")


`open(..., "r")` with `write()` raises runtime failure

main opens /tmp/.deepsource.toml in read mode and immediately writes to it. This always raises at runtime, breaking execution paths that reach this block.

Open with a writable mode such as "w" or "a", preferably via a context manager

+def tar_something():
+    os.tempnam("dir1")
+    subprocess.Popen("/bin/chown *", shell=True)


`subprocess.Popen(..., shell=True)` allows shell metacharacter execution

tar_something executes /bin/chown * with shell=True, so shell parsing controls execution. Crafted filesystem entries can inject extra arguments or commands under process privileges.

Replace with argument-list execution and disable shell parsing using shell=False

+def tar_something():
+    os.tempnam("dir1")

+    o.system("/bin/tar xvzf *")


`o.system` triggers `NameError` at runtime

tar_something calls o.system, but only os is imported. Runtime execution crashes with NameError, preventing subsequent operations.

Replace o.system with os.system, or preferably remove shell execution and use safe subprocess argument lists

+    elif x != 2 or x != 3:
+        print("also true")


`x != 2 or x != 3` makes later branches unreachable

check contains an always-true condition, so later comparisons never execute. This creates dead code and hides intended decision logic.

Replace with x != 2 and x != 3 or invert using membership checks matching intended behavior

+    f = open("/tmp/.deepsource.toml", "r")
+    f.write("config file.")


`open(..., "r")` with `write()` causes immediate exception

The __main__ path repeats the read-mode handle write, so direct script execution crashes before finishing argument processing. This makes the entrypoint unreliable and masks later behavior.

Replace with with open(..., "w") or "a" and remove manual close()
